further provided i To all wkom'z't may concern: intended; and is c it known that I, Roemrr C. WALi, a usual metal roller or ball beari hub. t citizen of the United States, and resident ,shown) which fits through the ho o'finanfis. of Philadelphia, county of Philadelphia, and clamped upon OPfiOS G fac s f h 8P 9 em as is custo 09 be understood, that as State of P Improvement in Wheels, lowing is u specification.

The object at my invention is to provide in spokes and wheels- 7 body sima circle or wheel as accuracy of manufacture, and hence to insure the pro strength and durability. the spokes arefirst joined to My invention has for it further object, the circular wheel; parts, each com making of the spoke members in such form equal number of spokes,

trees may be interample shown), and these may to form a continuous solf-sustainby a. sliding movement of hog hub portion, the assembling being easy the other in al of accomplishment and inex )ensivcgr ves t0 b 6n aged. T l With these and other 0 jects specified are made quite mllow hereinafter, my invention consists in the construction of t] spoke and combination of a plurality of said spokes to constitute a wheel structure, fully described in connection with t e accompanying drawin 's and pointed out in the claims. referring to the drawings, Figure 1 is a side elevation of u Wheel embodying my invention with a. portion of the folly removed; Fig. 2 is a cross section of n portion of the same taken on linf e zv w of Fig. 1; Fig. 3 is a perspective View of one of myimproved spokes; Fig.4 is a side elevation similar to Fig. 1 but with a slightly difierent construction of spokes; Fig. 5 is a cross section of the same on line 1 1 of Fig. 4; and Fig. 6 is aperspective view of the spokes employed in the wheel of Figs. 4 and 5.

Referring to Figs. 1, 2}an'd 3, the spokes 2 are each provided with a V-shapcd hub section 3 having one of its inclined edges provided with a dovetail rib 6 and the other inclined ed e with a corresponding dovetail groove? (Fig. 3); and when these hub sections of adjacent spokes are interlocked these, as in the other example, -1n =3 hown in Figs. 1 and 2, t ey are not l ck o hold the spok held in a circular; arrangement, but

against lateral displacement. and 6, it Will be seen kes are thus interlocked, they V-slmped hub section 8 of the spo are also glued in position one upon the other grooved as at 7 to provide tongues 6' and walls 9 continuous with one of the.

enusylvama, have invented, on parts 3, bracing t of which the fol- It will FY so as not to consume needless lumber, and also to avoid weakness which would result from too deep a groove.

y reason of this shallowncss of the to or rib 6 and groove 7, the semi-circular parts may be assembled without excessive binding, but all binding may be obviated by providing one of the end spoke hub tions 3 of one semi-circular partwith two grooves T and the adjacent end spoke sec,- tion of the other semi-circular part with two ribs in Fig. 1.

or ribs 100 so as to provide an integral hub to the wheel with a central aperture 5. In ractic'e, the walls of the grooves. These spokes have the wooden" wheel thus-formed is fitted with n. grooves and ton es or ribs directed latorally instead of in and each of the edges 9 have both a rib 6" and a groove 7", but said parts at the two edges are oppositely di rected; as will be seen from Figs. 5 and 6. These spokes may be assembled as in the first described example, in which the two semicircular parts of the wheel are first formed and then united by sliding them together along one diameter; or instead, the spokes may be assembled by interengaging them from the side throughout the entire circle, though in the engaging of the last section 9 the same will have to be sprung in at both sides (Fig. 5). The grooves 7" and the ribs 6 are made quite shallow so as not to Weaken the spoke. These spokes are also glued together when being assembled, so that the wheel is self-sustaining when completed and the glue is dry.

Wheels of this class are especially adapted for automobiles and the radlal length of the spokes may be cut to suit the diameter of the wheel required; the particular application of the folly and tire is separate from my invention, which relates solely to the con struction of the wooden spokes and their asssemblage into a circular wheel ready for the folly and metal axle hub and hearing.

it will now be apparent that I have devised a novel and usei'ui construction which embodies the features of advantage enumerated as desirable. and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfimtory and reliable results, it is to be understood that; I do not restrict myself to the details, as the same are susceptible of modification in various particulars without departing from the spirit or see c of the invention.

Having now deseri ed my invention, what I claim as new and desire to secure by Letters Patent, is

1. A wheel structure consisting of aphrrality oi: spoke members each having a V- slmped hub section and which when asscmblvd provide a continuous hub with radiating spokes, the opposite edges of all of the hub sections except two respectively provided with a rib and a groove and of theremuining two hub sections one of whieh'is provided on both its edges with ribs and the other provided on both its edges with grooves, said ribs and grooves of all of the hub sections arranged radially and interlocking in pairs to unite the adjacent hub sections to prevent the spoke members separatformed on the edges of the hub sections to constitute a permanent part thereof.

2. A wheel structure consisting of a plurulity of spoke members each having a V- shnped hu section v and which when asscmbled provide a continuous hub with radiating spokes, the abutting edges of the hub sections united by interlocking ribs an grooves integrally formed with said hub .s'ri'ii nis, sa id ribs. and grooves arranged radially of the hub and said interloekin hub sections having their interlocking ribbe ninl grooved edges made of complementary forms, whereby a rib of one section will inlixllnvk with a groove of the next adjacent swfiion to prevent said spokes separating radially andeircumferentially in testimony of which invention, I hereunto set my hand.
